Hi All, I have a very basic question about streaming replication feature of Postgres. Let’s assume I have servers A, B, C, D, & E with postgres installed with streaming replication as follow: A à B ( sync replication ) A à C ( async replication ) A à D ( async replication )
A à E ( async replication )
A is master & rest are slaves. Now my question is: Assume replication link between A & B may/may not stable. If A goes down, how will I choose my new master from slaves? What are criteria to choose new master?
Thanks, Sacheen Birhade |
